Question 1

Which of the following answers describes a reason for adopting experience-based testing techniques?

AExperience-based test techniques provide more systematic coverage cnteria than black-box and white-box test techniques

BExperience-based test techniques completely rely on the tester's past experience for designing test cases.

CExperience-based test techniques allow designing test cases that are usually easier to reproduce than those designed with black-box and white-box test techniques.

DExperience-based test techniques tend to find defects that may be difficult to find with black-box and white-box test techniques and are often useful to complement these more systematic techniques.

Answer : D

Experience-based testing techniques leverage the tester's intuition and prior experience to identify defects that systematic techniques might miss. These techniques are valuable because they can uncover issues based on real-world usage and scenarios that aren't always covered by more formalized black-box and white-box methods. The ISTQB CTFL Syllabus v4.0 highlights the complementary nature of experience-based techniques in providing a broader defect detection strategy.

Question 2

Which of the following statements about white-box testing is FALSE?

AStatic testing can benefit from using code-related white-box test techniques during code reviews.

BWhite-box testing allows suggesting test cases for increasing coverage levels which are based on objective measures

CAchieving full code coverage for a component or a system ensures that it has been fully tested

DBlack-box testing can benefit from using code-related white-box test techniques to increase confidence in the code.

Answer : C

Achieving full code coverage does not guarantee that the component or system is fully tested or free of defects. Code coverage metrics indicate the extent to which the source code has been tested, but they do not account for the quality of the tests or whether all possible scenarios have been considered. Other types of testing, including functional, performance, and security testing, are necessary to ensure comprehensive testing. The ISTQB CTFL Syllabus v4.0 highlights that while high code coverage is beneficial, it does not equate to complete testing.

Question 3

Which ONE of the following statements BEST applies to checklist-based testing?

AChecklists should contain general guidelines to ensure that all aspects of the software are covered.

BChecklists should contain specific test conditions that can be individually and directly checked.

CChecklists should primarily consist of automated test cases to maximize efficiency.

DChecklists should be used exclusively for functional testing, as they are unsuitable for non-functional testing.

Answer : B

Comprehensive and Detailed In-Depth Explanation:

Checklist-based testing uses specific test conditions (B) that help testers ensure key aspects are validated. The checklist items can be derived from past defects, requirements, or regulatory standards.

(A) is incorrect because general guidelines lack specificity.

(D) is incorrect because checklists are useful for both functional and non-functional testing (e.g., security, performance).

Checklists help ensure completeness without enforcing strictly scripted execution.

Question 4

An alphanumeric password must be between 4 and 7 characters long and must contain at least one numeric character, one capital (uppercase) letter and one lowercase letter of the alphabet.

Which one of the following sets of test cases represents the correct outcome of a two-value boundary value analysis applied to the password length? (Note: test cases are separated by a semicolon)

A1xA;aB11;Pq1ZZab;7iDD0a1x

BaB11;99rSp:5NnN10;7iDD0a1x

C1xB: aB11: 99rSp: 5NnN10; 4NnN10T; 44ghWn19

D1RhT;rSp53;3N3e10;8sBdby

Answer : D

The correct outcome of a two-value boundary value analysis applied to the password length is the set of test cases represented by option D. Boundary value analysis is a test design technique that focuses on the values at the boundaries of an equivalence partition, such as the minimum and maximum values, or the values just above and below the boundaries. A two-value boundary value analysis uses two values for each boundary, one representing the valid value and one representing the invalid value. For example, if the valid range of values is from 4 to 7, then the two values for the lower boundary are 3 and 4, and the two values for the upper boundary are 7 and 8. The test cases in option D use these values for the password length, while also satisfying the other requirements of the password, such as containing at least one numeric character, one capital letter, and one lowercase letter. The test cases in option D are:

1RhT: a 4-character password that is valid

rSp53: a 5-character password that is valid

3N3e10: a 6-character password that is valid

8sBdby: an 8-character password that is invalid The test cases in the other options are incorrect, because they either use values that are not at the boundaries of the password length, or they do not meet the other requirements of the password. For example, the test cases in option A are:

1xA: a 3-character password that is invalid, but it does not contain a capital letter

aB11: a 4-character password that is valid

Pq1ZZab: a 7-character password that is valid

7iDD0a1x: an 8-character password that is invalid Reference: ISTQB Certified Tester Foundation Level (CTFL) v4.0 sources and documents:

Question 5

For the same financial institution in Question 12, with the same requirements and expectations, what would be the most likely investment values used in testing if two-point boundary value analysis is used to design test cases specific to the 13% interest rate equivalence partition?

AR100 000, R100 001, R500 000, R500 001.

BR99 999, R100 000, R499 999, R500 000.

CR100 000. R500 000.

DR99 000, R500 001.

Answer : A

For boundary value analysis, the test cases should include the boundary values just inside and just outside the equivalence partition for the 13% interest rate range:

R100,000 (just inside the previous range)

R100,001 (start of the 13% range)

R500,000 (end of the 13% range)

R500,001 (just outside the range)

These values ensure that both the edges of the partition are tested.

Question 6

The following rules determine the annual bonus to be paid to a salesman of a company based on the total annual amount of the sales made (referred to as TAS).

If the TAS is between 50k and 80k, the bonus is 10%. If the TAS exceeds 80k by a value not greater than 40k, the bonus is 15%. Finally, if the TAS

exceeds the maximum threshold which entitles to a 15% bonus, the bonus is 22%.

Consider applying equivalence partitioning to the TAS (Note: 1k = 1000 euros).

Which one of the following answers contain only test cases that belong to the same equivalence partition?

ATC1 = 81 k; TC2= 97k; TC3=111k; TC4=118k

BTC1 = 40k; TC2= 46k; TC3=51k; TC4=53k

CTC1 = 79k; TC2= 80k; TC3=81k; TC4=82k

DTC1 = 90k; TC2= 110k; TC3=125k: TC4=140k

Answer : A

This answer is correct because equivalence partitioning is a test design technique that divides the input domain of a system or component into partitions of equivalent data, such that each partition is expected to produce the same output or behavior. Equivalence partitioning aims to reduce the number of test cases by selecting one representative value from each partition. In this case, the input domain of the TAS can be divided into four partitions based on the bonus rules: less than 50k, between 50k and 80k, between 80k and 120k, and more than 120k. The test cases in the answer belong to the same partition, which is between 80k and 120k, and they are expected to produce the same output, which is a bonus of 15%.

Question 7

Which ONE of the following tools would be MOST SUITABLE for facilitating the creation of test cases, test data, and test procedures?

ATest design and implementation tools are specifically designed for creating test cases, test data, and test procedures.

BStatic testing tools as they assist the tester in conducting reviews and static analysis.

CDevOps tools, as they support the automated build process and CI/CD.

DTest execution and coverage tools facilitate the automated execution of tests and the measurement of test coverage.

Answer : A

Comprehensive and Detailed In-Depth Explanation:

The correct tool for creating test cases, test data, and test procedures is a test design and implementation tool (A).

(B) is incorrect as static testing tools focus on code analysis, not test case creation.

(D) is incorrect because test execution tools focus on running tests rather than designing them.

Test design tools help optimize test coverage, reduce redundancy, and improve efficiency.
